surface c inclin-ing from its central downwardly and outwardly toward the periphery of .the valve, such inclined surface terminating at such periphery. llhe valve is supported upon a stem C', which passes through a bushing as forming part of the casing. The lower end of the valve stem is threaded and the diameter of the bore in the made substantially equal to the portion lBe it known that l., ARTHURG. MCKEE, a. citizen of the United States, resident of Cleveland, county of Cuyahoga, and State hio, have invented improvementin Gas-Burners, of which the lo lowing is a specification, l y

invention being herein explained and the best mode in which l. have contemplated applying that principle, so as to distinguish it from other inventions.

y invention relates to gas burners, and particularly to that class of burners used for delivering the ing the heat such and the like.

The object of my invention is to produce a burner of the above described character which will be economical-in its construction and efficient in its operation.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.-

The annexed drawing and the following description setforth in detail certain means embodying the invention, the disclosed means, however, constituting but one of va,- rious mechanical forms in which the principle of the invention may be applied.

In said annexed drawings :`li`igure l is a vertical axial section of a gas burner embodying my invention, together with a broken section of a gas main to which such burner is attached, a sectional portion of the boiler being also shown in connection therewith. Fig. 2 is an elevation of the mechanism shown in Fig. 1.

The apparatus as illustrated in the draw- .ings consists of three principal parts, the valve-casing, the valve and valve-actuating mechanism, and the nozzle. rlhe Casin A is secured to the main B by means o an intermediate connection A', which for the purpose of this application, may be considered a part of the valve-casing. Secured between the ca-sin l' A and the connection A a ring A2 formed with a circular opening which constitutes the valve-opening- That of the cylindrical portion of the stem being also equal to the diameter of such bore. will therefore be notedthat the stem ma' necessary gas for producslide vertically in the bushing. Suitable as is required in boilers grooves a are provided in the bushing which form an air or well known, and used for like purposes. A feather a? is fixed to the bushing and extends horizontally into an elongated slot c', shown in `dotted lines in Fig. 2. This feather prevents the stem C from turning when it is moved longitudinally in the bore of the bushing.

rlhe lower end of the stem is made of a length suiiicient to project soine distance out of the bushing and such projecting portion is engaged by a nut C2 provided with a hand wheel 3 lt will therefore be seen that by turning the hand wheel, and consequently the nut, the valve-stem and the valve may be moved in the direction of ltheir common axis, and the valve therefore seated or unseated, as desired. That terior of the valve-casing shown, so as to form a substantially conical surface.

site and below the valve-seat, and it is made to terminate inwardlyso as to bring the periphery of the valve vertically above saine. Any dust or dirt which is discharged from the upper surface of the valve will therefore drop upon the inclined surface a3 and will be carried downwardly and outwardly. One side of the casing is provided with an opening to which is suitably attached an intermediate nozzle member D, part of the ring A2 upon the lower edge to whose outer surface issecured the nozzle thereof and surrounding the opening conproper, D. The inner surfaces of the noz stitutes the valve seat and the parts are so ar- ,zle and the member D are made continuous ranged as to cause this seat to assume a horiwith each other, as shown, and the lower zontal position, as shown.

part of the member is made continuous Arranged so as to be movable vertically with the conical surface a3. By this means, and to engage the valve seat from below is a the `dust and dirt deposited upon the said bell-valve C, which is formed with an upper inclined surface will `be carried around and gas packing, such as is This, inclined surface is therefore located oppo,

-be controlled out of the nozzle Without obstruction, as will be readily understood.

It will therefore be seen that by means of the above described construction, the flow of the gas from the main into the nozzle may as desired, and all dust and dirt which might tend to destroy the valve seat or interfere with the operation of the valve is automatically removed from the interior of the casing and its deleterious effect thus eliminated.

Having fully described my invention, what I claim therefore and desire to secure by Letters Patent is 1. In a device ofthe class described, the combination of a valve-casing provided with an upper gas-inlet, a gas-outlet, and a substantially horizontal valve-seat surrounding said inlet; a bell-valve below said seat and adapted to engagethe same; means for actuating said valve from beneath said casing; and a nozzle connected with said outlet.

2. In a device of the class described, the combination of a valve-casing provided with an upper gas-inlet, a gas outlet, and a substantially horizontal valve-seat surrounding the inlet, that part ofthe valve-casing below and opposite the valve being removable, whereby such valve may be removed; means for actuating the valve; and a nozzle connected with said outlet.

3. 'In a device of the class described, the

' combination of a valve-casing provided with said inlet, that part of an upper gas-inlet, a gas-outlet, and a substantially horizontal valve-seat surrounding the valve-casing opposite and below said valve-seat being removable so as to form an opening through which said valve may be removed; a valvestem connected with saidvalve seated in said removable casing portion; and means for actuating said stem longitudinally, so as to actuate said valve to seat, and unseat; and a nozzle connected with said outlet.

4. In a device of the class described, the combination of a valve-casingy forming a valve-chamber, and provided with an upper gas-inlet and a lateral gas-outlet; a valve within said chamber; and means for actuating said valve to seat and unseat; the

ranged to move in face located vertically bottom of the interior of the valve-chamber being flush with said outlet, whereby the movement of the gas through the chamber will prevent the accumulation of solid matter therein.

5. In a device of the class described, the combination of a valve-casing forming a valve-chamber, and provided with an upper gas-inlet and a lateral gas-outlet; a valve within said chamber; means for actuating said valve to seat and unseat; the bottom of the interior of the valve chamber being flush with said outlet, whereby the movement of the gas through the chamber will prevent the accumulation of solid matter therein; and a nozzle connected with said outlet and having its lower surface flush therewith.

6. In a device of the character described, the combination with a valve-casing provided with a gas outlet, a gas inlet, and a substantially horizontal valve seat surrounding said inlet, the bottom of the interior of the valve-casing being provided with a downwardly and outwardly inclined surbelow and of greater diameter than said seat; of a bell-valve and means for seating and unseating same.

7. In a device of the class described, the combination of a vak-'erasing provided with a gas-inlet, a gas-outlet, a substantially horizontal valve-seat, and a downwardly and outwardly inclined surface opposite' and below said seat; a bell-valve and means for seating and nnseating same; said valve arthe space intermediate of said seat and surface, and having a downwardly and outwardly inclined upper surface terminating at the valves periphery, the latter being located vertically above said first-named downwardly and outwardly inclined surface; and a nozzle connected with said outlet and having its lower surface continuous with said last-named downwardly and outwardly inclined surface.
